CONNECTING TO A HOST TERMINAL
Six Legend Plus units are used to monitor and
control parts packaging machines in a plant. The
Legend Plus units are located at each machine in
the p roduction area o f the building. A
communication line is run to an Industrial
computer located in the production office. The
drawing shows the line connection. Each Legend
Plus is programmed for a different address and are
all programmed for the same baud rate and parity
as the computer (ex. 9600 baud, parity even). An
application program is written to send and receive
data from the units using the proper commands.
